NECK-YOKE CENTER.

SPECIFICATION forming part of Letters Patent No. 781,012, dated January 31, 1905.

Application filed Iuly '7, 1904. Serial No. 215,660.

T @ZZ whom, it may concern:

Beit knownl that I, SAMUEL J.MoDoi\IALD, a citizen of the United States, residing at Gallatin, inthe county of Daviess and State/of and exact description of the same, reference being had to the annexed drawings, makingal part of this specification, and to the letters of reference marked thereon. p

The present invention has relation to that n class of neck-yoke centers embodied in my whereby the same is materially enhanced in' patent datedNovember 18, 1902, No. 714,013,

and is designed as an improvement thereon,

effectiveness and rendered more practical; and it consists in a neckyoke center constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a perspective View 'of a neck-yoke center embodying my improvement; Fig. 2, a side elevation, partly ,in section; Fig.3, a perspective View of the lower section ofthe latch;

In the accompanying drawings, A represents the pole-tip of a vehicle, provided with the usual inclined 'abutment-flange a, and Bv the neck-yoke bar connecting therewith, said bar having the clip-band O connected thereto, which band isalso connected to a double-extension locking-latch through the medium of a screw-bolt b and nut c, engagingthe screwthreaded end of the bolt. The bolt b extends through flanges d, projecting from the ends of the clip-band C, and alsothrough 'an eye' l e upon the section -D of the double-extension locking-latch, said section being pivoted to a coupling-ring E upon the end of the pole-tip.

The means preferably employed for forming a pivotal connection between the clip-bandv C and the coupling-ring E resides in the pivot-bolt f, extending through the fianges g of the .coupling-ring. and through an eye of the locking-latch section D.

The latch-section D comprises a projecting cam e' and a depending pusher-nger j', and the section F of the latch comprises a curved bearing-face 7c upon its upper side and a transverse groovel upon its under side, as shown l more clearly in Fig. 3 of the drawings.

grooveZ upon the under side of the latch-section F fits over a transverse pin m, which extends through the iianges g of the couplingring E, whereby said latch-section is held in place upon the pole-tip. The section D of the latch tilts back and forth, and bearing with The l more'or less frictional contact with the latchsection F through the action of the cam t' will securely lock the coupling-ring E to the pole-tip. When the latch-section D is tilted back, the depending push-finger y' will bear against .the rear end 'of the latch-section lF and draw the coupling-ring E against the under side of the pole-tip and securely hold it in position and provide a perfect antirattler and enables one and the same couplingring to lit various-size pole-tips.

The locking. device herein described is both simple and effective and prevents the neckyoke and its connections from striking the pole-tip when the team is hitched, and if the trace, doubletree, or swingletree should break the latch will come into action as a locking medium.

It is evident that many changes or modiiication may be resorted to in the several details of construction, and any suitable vlatch device which will act on the coupling-ring of the pole-tip tolockor release it may he substituted for the device shown without in any manner departing from the spirit of the invention.

Having now fully described my invention, what AI claim as new, and desire to secure by Letters Patent, is-

1'. A neck-yoke'center, comprising a clipband for attachment tothe neck-yoke bar and a coupling-ring upon the pole-tip, a lockinglatch connecting with the clip-band and with IO engage the transverse bearing pin or bar, said push-linger being disposed to directly engage the end of said bearing-surface, substantially as and for the purpose set forth.

In testimony whereof l aiix my signature in presence of two witnesses.
